how do u turn protected songs to unprotected songs?

I am not sure what you mean, "protected" songs; all commercial music is copywrite protected by law. Althought it is common practice to download copywrited music, it is illegal. If you are referring to some kind of software protection that you want to crack, this forum's rules prohibit the giving of such information. Since I have answered your question and cannot furnish any more, this thread is closed.
